Continuity mistake: Heyes' horse is shot out from under him by the Chiracahua, forcing him to leave it behind and ride double with Curry. But when they return to Apache Springs, Heyes is again riding the same horse that was shot earlier. (00:40:40 - 00:43:30)

Continuity mistake: In memory of their friend Seth, who died in "Smiler with a Gun," Curry grew a mustache that he kept for several months. (As a running joke, Heyes kept prodding him to get rid of it and Curry kept refusing.) Because production and air dates differed, the mustache is, without explanation, missing here. It's back in the next episode, gone again in the next, and reappears for the last time in the next, where Curry finally shaves it off.

Continuity mistake: During the dinner, Grace is in two places at once in the background. She's at the far right end of the bar drying a glass when the camera is on Mr. Fielding. When the camera reverses angles to show Mrs. Fielding, Grace has instantly jumped to a spot at the far left end of the bar, and is still drying the same glass. (00:12:15)
